Reply to "What's the difference between these LCRUs?"

Thanks Roy, but what I'm after is the exact differences. Do the last two on the list have announcements or crew talk where they actually say the cab number? Do the first two actually say the road name in their crew talk? Etc. I'm guessing (and I assure you, it IS a guess) that these are all LCRU2s, so there are no differences in the hard wiring? Certainly the chips must be different, but what do those differences translate into?

I am still in the newbie stage, owning just two functioning TMCC equipped units, one an FM Trainmaster, the other a GP9, so I'm looking at Lionel's sale coming up in November and am considering purchasing a couple of these to go into my other Pullmore equipped engines - I'd like to know the details.

Thanks!
